Spring Centre Clutch
The clutch is set up correctly on its initial build, but bedding in
of the friction surfaces may necessitate adjustment to remove
excessive free pedal travel after a few hours use. Subsequent
adjustments will be at lengthy intervals if the machine is used
correctly and the clutch is not abused by slipping.
Routine Adjustment
Adjustment stops 1 and 2 are preset and normally require no
adjustment.
When correctly adjusted, the clutch pedal should have 20-
25mm of free pedal movement before resistance is felt.
In order to obtain the correct 20-25mm free pedal travel :-
z Slacken both locknuts on the clutch operating rod.
z Turn the operating rod in the correct direction to reduce or
increase the effective length of the operating rod until pedal
travel is correct. Retighten the locknut.
z If greater clutch adjustment is required remove pinch bolt
and clutch arm from the serrated clutch withdrawal shaft
which passes through the bell housing.
Reposition the lever arm on shaft after moving it clockwise
one serration. Refit pinch bolt and tighten. Repeat the
instructions for adjustment as above.
Take great care when repositioning clutch arm as only a small
movement of this lever can seriously affect clutch performance
